I have seen a huge amount of confidently staggeringly wrong political takes on HN. I'd say on par with any other platform.
It's a disease spread by math and physics profs dismissing other domains, and weirdly prevalent in an industry solely concerned with gluing together different points of view. The poor kids that don't take common core seriously never pick up the conceptual framework everything depends from and are simply unable to reason about ideas that need to be connected together.
The secondary (and on from there) effects of most of their views are not considered, and so their views are not internally consistent at all.
Small government! (why do I have to wait so long for my support payment query to be answered?)
No immigration! (why can't I find someone to clean my house on the cheap?)
